 of their extent; but in no case in the grounds passed over in 

 this journey did the local glaciers from the Andes appear to 

 have extended across the valley and reach the coast range.

GLACIERS IN ALGERIA. 



Mr. Charles Grad, a well-known scientific writer, an Alsa- 

 tian by birth, but resident in Paris, has lately visited Alge- 

 ria for the purpose of deciding upon its availability for col- 

 onization on the part of such of his compatriots as prefer to 

 live under French rule .abroad to remaining in their own 

 country under German dominion. In addition to the special 

 objects of his mission, he has been devoting much of his time 

 to the determination of various scientific questions. He has 

 published papers upon the magnetic declination of Algeria, 

 and has also been inquiring into the glacial phenomena of 

 the mountains of Northern Africa. Among other observa- 

 tions he discovered the existence of enormous moraines on 

 the slopes of the mountains turning toward Sahara. He also 

 expected to find traces of old glaciers in Djurdjura and the 

 mountains of the great Kabylia. From daily observations 

 in regard to the sea temperature at La Calle, Algiers, and 

 Oran, and during a journey along the Algerian coast in De- 

 cember, he found the temperature on the high seas during 

 the month to be from 56 to 59 F. 17 C.June, 1872, 229. " 



GLACIAL ACTION NEAR MONTEVIDEO. 



A communication was presented to the National Academy 

 of Sciences at its annual meeting on the 16th of April last, 

 from Professor Agassiz, dated Montevideo, February 26. In 

 this he expresses his gratification at finding evident traces 

 of glacial action in the vicinity of Montevideo, as shown by 

 the occurrence of phenomena which were quite satisfactory 

 to his mind. He leaves the question undecided as to the 

 origin of the erratic boulders found scattered over the sur- 

 face, but hopes that his further investigations in the southern 

 hemisphere will enable him to supply the necessary data.
